Relationship between drag on an aircraft and other variables
The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot").[1] Drag may be expressed as actual drag or the coefficient of drag.
Drag curves are closely related to other curves which do not show drag, such as the power required/speed curve, or the sink rate/speed curve.
